ABSTRACT:
The capacitance of a pixel of an active matrix liquid crystal light valve is increased without reducing its optical transparency by adding polysilicon islands under the adjacent gate lines, degeneratively doping the islands to render them conductive under operating conditions, thermally oxidizing the islands to form dielectric layers, depositing gate lines over the dielectric layers to form extra capacitors, and connecting the islands to the adjacent pixel electrodes. Such active matrix displays are advantageously employed in a color projection TV to produce the separate red, blue and green components of a full color display.
